THREAD-HOLDIN G DEV-ICE.

1913. Serial No. 767,298.

To all whom it may concern:

. Be it known thatll, JOHN KIEWICZ, a citison of the United States, residing at Hyde Park, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Thread-Holding Devices, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to thread holding devices such, for example, as are adapted to be attached to. sewing machines for, securing the loose thread end at the beginning of a sewing operation.

For convenience, the present invention is shown as applied to a portion of a machine for attaching buttons to fabric. ihe novel thread holding device is shown associated with the work plate of such a button attaching machine, as is illustrated in "my prior co-pending application Serial No. 691,652, filed April 18, 1912, of which prior application this present application is a division.

The main object ot the present improvement is to increase the simplicity and also the durability of thread. holding devices while retaining equal or greater .efiiciency than prior known devices.

Other objects will be statedin the herewilibe apparent to those skilled in the art.

To the attainment of such objects the present invention consistsin the novel con-' combinations structions, features and do.-

First will be described one form of thread holding device embodying the present improvements, and thereafter the novel features will be pointed out in the claims.

In the accompanying drawings forming a part hereof, .lFigure :l. is a left-hand elevation of a sewing machine work support togetherwith thread holding device carried thereby; Fig. :2 is a top view of the parts Fig. 3 is an enlarged partial vertical section of the work support and figures.

Similar letters of reference designate corresponding parts in the several figuresof the drawings. g

While in the annexed drawings the novel thread holding device hereof ciated. with the work support, it might in some cases be associated with the opposed .e-iw tjashort piece or tongue struck out ofthe "material of a sheet metal tion so as to pass'through spring. member whose holding end presses against the work clamping member and whose other end is secured so as to allow play of the hold comprises a substantially horizontal plate centrally slotted at f to permit the sewing operations. The improved thread holder mounted thereon is shown as consisting of an elougated spring member M, whose one end is secured at m, so as to. permit play or movement of the other end, which latter is the holding ,3 end -.m.- cooperating with the plate f for holding a thread between them. There has been a difficulty with the ordinary thread holding device that the forcible engagement of heavy thread therein oft repeated graduallyrbends and wears the device so as to sometimes destroy it or at least impair its eiiiciency. These objections-were the typeof, holding device consisting part such as the work support. Such objections are entirely overcome in the present improvement, in which is comprised an elongated member controlled by spring action, so arranged as to coiiperate with another member for holding the threadbetween them, the elongated holding device having a degree of play about a distant point, V end, so that no wear or destruction is probable. The holding device M is shown as consisting of a piece of elastic wire fixed by a screw at m and yielding at its other end by reason of the play of its own elasticity. An etfective construction and fitting or the device is that shown, wherein the spring wire M is reversely bent at an intermediate poran aperture in the plate f, the extreme end m only showing to view above the work support. The tend- A CORPORATION OF Patented Sept. 29, 1914. Serial No. 691,652. Divided and this application filed May 13,

namely its farther ency of the spring action is to hold the end m of the spring member M downwardly in pressing contact with the plate f, while the aperture in said plate is sufiiciently large to permit the holding end m to slightly rise for the admission of the thread, and the extreme end of the wire is beveled as shown to facilitate the thrusting of the thread into the thread holder.

The improvement may be expressed as a device for holding thread ends on sewing machines which device comprises the combination of the following elements, namely, a fixed plate-like portion F of a sewing machine, an elongated spring strip member M shaped and arranged to have its thread holding end 'm/ pressing flatwise directly against said fixed member with the thread between them and its other end stationarily rather than movably secured to the fixed member; and the mentioned parts so constructed as to restrict the play of the strip member within narrow limits, namely, by reason of the strip member having its se cured end at one side of the fixed member and its holding end at the opposite side.

It will thus be seen that a thread holding device has been described which embodies the principles and attains the objects and advantages before referred to, and other advantages will be apparent to those skilled in the art.

\Vhile the improvement has been described in detail, obviously matters of detail and form may be indefinitely varied within the principles of the improvement and, therefore, no restriction to such matters of detail or form is intended excepting as set forth in the appended claims.

What is claimed is:

'1. A device for holding thread ends on sewing machines comprising in combination having its secured end with a fixed plate-like portion of a sewing machine, an elongated spring strip member, shaped and arranged to have its thread holding end pressing flatwise directly against said fixed member with the thread between them and its other end stationarily secured to said fixed member, said strip member having its secured end at one side of the fixed member, and its holding end at the opposite side.

2. A device for holding thread ends on sewing machines comprising in combination with a fixed plate-like portion of a sewing machine, an elongated spring strip member,

shaped and arranged to have its thread holding end pressingfiatwise directly against said fixed member with the thread between them and its other end stationarily secured to said fixed member, said strip member at one side of the and its holding end at the and reversely bent at the passing the fixed members plane.

device for holding thread ends on machines comprising in combination fixed member, opposite side, point of sewing with a fixed plate-like portion of a sewing machine, an elongated spring strip member, shaped and arranged to have its thread holding end pressing flatwise directly against said fixed member with .the thread between them and its other end stationarily secured to said fixed member, the fixed member having an aperture, and the strip member passing through said aperture and there reversely bent so that its two ends lie against opposite faces of the fixed member. In testimony whereof I afiix my signature in presence of two witnesses.
